Abstract

ABSTRAKTeknologi Automatic Speech Recognition (ASR) telah berkembang pesat sebagai alat untuk meningkatkan aksesibilitas informasi bagi penyandang tuna rungu, terutama melalui video. WAV2Vec 2.0, salah satu teknologi ASR unggulan, efektif dalam transkripsi teks, namun kinerjanya menurun saat menghadapi noise. Penelitian ini bertujuan mengoptimalkan WAV2Vec 2.0 dengan menerapkan Spectral Masking untuk mengurangi noise tanpa mengorbankan kejelasan sinyal utama. Evaluasi dilakukan pada tiga jenis video: podcast, video dengan background noise, dan video dengan background music. Hasil menunjukkan penurunan Word Error Rate (WER) yang signifikan, sebesar 78.06% pada podcast dan 53.85% pada video dengan background noise. Hasil penelitian menunjukkan bahwa Spectral Masking efektif dalam meningkatkan akurasi transkripsi, menawarkan solusi inovatif untuk aksesibilitas tuna rungu dalam kondisi audio yang kompleks.Kata kunci: noise reduction, spectral masking, tuna rungu, WAV2Vec 2.0 ABSTRACTAutomatic Speech Recognition (ASR) technology has rapidly evolved as a tool to enhance information accessibility for the hearing impaired, particularly through video content.

Abstract

Optimizing MQTT broker performance is crucial for maintaining efficient message routing in IoT systems, especially under varying workloads and QoS levels. This study compares the Round Robin (RR) and Least Response Time (LRT) algorithms to evaluate their performance across QoS levels 0, 1, and 2 and client loads ranging from 500 to 2,500 clients. Using Apache JMeter, key metrics such as CPU usage, throughput, delay, jitter, and response time were assessed. LRT was found to excel in enhancing response time and reducing delay, particularly under high client loads and in applications requiring minimal latency. However, this comes at the cost of higher CPU usage under heavy loads. In contrast, RR demonstrated optimal performance in maintaining balanced CPU utilization and predictable performance, though with slightly higher response times. Both algorithms demonstrated linear scalability in throughput, confirming their ability to handle increasing workloads without bottlenecks. These findings offer practical guidance for IoT developers: in latency-sensitive environments such as industrial automation, LRT is preferable due to its low-latency benefits, while RR is better suited for resource-constrained IoT systems like environmental monitoring, where stability and even load distribution are prioritized. The trade-offs identified provide valuable insights for selecting appropriate algorithms based on specific application requirements.

Abstract

East Java is one of the areas that has many cases of covid 19, therefore the East Java provincial government must increase the number of cases of covid 19 in East Java, including by promoting the health protocol program 5. The pattern of data on cases of covid 19 in East Java shows fluctuating data patterns. Forecasting that can be used is the triple exponential smoothing method. From the test results obtained accuracy of 71.25%. It is hoped that the forecasting results can later be used as a reference for formulating East Java provincial government policies for the next period.

Abstract

Penelitian ini bertujuan untuk menganalisis penempatan access point (AP) pada jaringan WLAN STMIK Asia Malang, yang berdampak terhadap level daya atau kuat sinyal yang diterima oleh pengguna. Pendekatan pertama melalui site survey, dengan tujuan yakni mendapatkan informasi yang cukup mengenai jumlah dan penempatan AP yang saat ini diaplikasikan pada gedung kampus STMIK Asia Malang. Hasil dari walktest ini akan digunakan sebagai parameter untuk perhitungan teoritis menggunakan model propagasi One Slope Model (1SM). Berdasarkan perhitungan 1SM, didapatkan jarak optimal untuk penempatan AP tidak lebih dari 13 m pada propagasi LOS (rentang kuat sinyal -10dB sampai dengan -20dB, pada area koridor gedung) dan jarak 6 m pada propagasi NLOS (rentang kuat sinyal -40dB sampai dengan -50dB, pada area ruangan perkuliahan). Hasil analisis membuktikan bahwa keberadaan barrier mempengaruhi kekuatan sinyal yang diterima oleh user, sehingga penempatan perangkat WLAN, dalam hal ini AP perlu diperhatikan.

Abstract

The evolving cyber threats demand more sophisticated and accurate intrusion detection systems (IDS). This research develops a hybrid CNN-LSTM model with comprehensive data preprocessing techniques to enhance network attack detection accuracy. The UNSW-NB15 dataset consisting of nine attack categories and 49 features was used as research data. The methodology begins with data preprocessing including data cleaning, categorical transformation using categorical codes, class balancing with upsampling, StandardScaler normalization, and 80:20 data splitting. The hybrid model architecture combines three CNN blocks for spatial feature extraction with two LSTM layers for modeling temporal dependencies. The model was compiled using Adam optimizer with 0.0005 learning rate and equipped with EarlyStopping, ReduceLROnPlateau, and ModelCheckpoint callbacks. Evaluation results show the CNN-LSTM model achieves 99% accuracy, precision, recall, and F1-score, significantly outperforming the standard CNN model which only reaches 96%. Learning curves demonstrate rapid convergence without overfitting indication. This research proves that the combination of CNN's spatial feature extraction capability and LSTM's temporal dependency modeling is highly effective for anomaly detection in complex sequential data such as network traffic.

Abstract

Software Defined Network (SDN) is a network modelling that separates the control plane and data plane. SDN is a new form of paradigm used for large-scale networks, one of which is for routing. Most types of routing used today use single-path routing. Single-path only uses one path as data transmission. This will result in reduced performance on the network which is often referred to as network congestion. In this test, the routing algorithm used is Breadth First Search (BFS) by modifying the path so that congestion on the network can be minimised. The BFS algorithm is implemented using Mininet emulator, Ryu Controller, and fat-tree topology. In the test, 20 scenarios were used with a bandwidth of 50 - 1000 Mbps within 15 seconds. Tests were conducted to measure the performance of the BFS algorithm, namely the path and QOS (Quality Of Service) parameters which include testing delay, packet loss, jitter, and throughput. The data obtained in testing using the conventional BFS algorithm is compared with the modified BFS algorithm data in the same test method. In path testing, the modified BFS algorithm is superior and in parameter testing, it is produced with a degraded percentage value in delay (65%), packet loss (99%), jitter (84%), and throughput has increased by (41%). So the modified BFS algorithm is superior due to the utilisation of path modification for routing optimisation which is more effective in handling network congestion.

Abstract

Berlangganan kapasitas bandwidth yang besar tidak selalu memberikan jaminan bahwa layanan yang diberikan kepada pengguna akan maksimal. Tanpa adanya manajemen bandwidth yang tepat, maka pengguna dapat saja berebut internet dan terjadi sebuah ketimpangan bandwidth yang diterima. Pengelolaan bandwidth biasanya akan diimbangi dengan adanya pengelolaan user melalui konsep pemetaan tingkat prioritas user, dengan tujuan untuk mendapatkan hasil manajemen jaringan yang lebih baik. Untuk itu, penelitian ini secara khusus mengusulkan sebuah metode pengintegrasian skema manajemen jaringan dalam bentuk manajemen pengguna dan manajemen bandwidth. Manajemen pengguna dilakukan melalui pengklasifikasian pengguna berdasarkan tingkat kepentingannya masing-masing dengan menggunakan metode Hierarchical Token Bucket (HTB). Sementara manajemen bandwidth yang merata untuk seluruh pengguna diusulkan dengan mengintegrasikan konsep Per Connection Queue (PCQ) yang bersifat dinamis, tanpa membebani router. Hasil penelitian menunjukkan bahwa pengintegrasian metode PCQ-HTB memberikan sebuah alternatif baru dalam manajemen jaringan. Terjadi peningkatan nilai throughput yang dihasilkan mencapai 12,18 kali lipat, yang juga diimbangi dengan akses internet pengguna yang lebih merata.  Kata kunci: HTB, Internet Sekolah, Manajemen Bandwidth, Mikrotik, PCQ
